Un test technique est demandé Puis entretien avec un ingénieur de l'équipe Puis entretien avec le directeur de la tech ou le CEO Finalement, une offre vous est proposé si le feeling passe bien

First, there was a call with the CTO, which was mostly introduction to their Company with some basic questions (e.g "Where do you see yourself in 5 years?") After that I received quite a lengthy test task. I spent a few hours on it. In the end I received only a dry rejection email with no feedback on my solution. Not really sure what they expected there. My suggestion would be to proceed with the test task only if you really see yourself working there. Otherwise it's a complete time waste.
